WATCH-CASE STEM.

SPECIFICATION forming part of Letters Patent No. 338,503l dated March 23, 1886.

Application filed October 3, 1885.

To all whom it may concern:

Be it known that I, WALTER H. FITZ GER- ALD,of Brooklyn, in the county of Kings, and in the State of New York,have invented certain Improvements in the Manufacture of Watch- Case Stems; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure l is a perspective View of the parts of a watch-case stem as ordinarily construct ed. Fig. 2 is a like view of the same united. Fig. 3 is a central section of said stern through its axis. Fig. 4 is a perspective view of my casestem, and Fig. 5 is acentral longitudinal section of the same.

Letters of like name and kind refer to like parts in each of the figures.

In the construction'of watch case stems it has heretofore been the custom to form the body by boring and turning the body from a solid piece of metal, and the ring-sockets from separate pieces of metal, and to then insert and solder the latter within radial openings which were drilled in said stem. Casestems constructed in this manner are eXpensive,and in consequence of defects in workmanship, which are liable to occur, the ringesockets will sometimes become detached, in which event injury to the Watch-case or watch may result.

The object of my invention is to produce a case-stem which shall possess a maximum of strength and durability; and to this end said invention consists, as anew article of manufacture, in a Watch-case stem formed from one piece of metal and having protuberant ringsockets which are a part of and integral with its body, substantially as and for the purpose hereinafter specified.

Serial No.178,933. (No model.)

In the annexed drawings, A designates a Watchcase stem which is constructed from one piece of metal by boring through the same an axial opening, a, then'turning its exterior to the required form, and then drilling within its body two coinciding radial openings, a, for the reception of ringsockets a2, which sockets are separately formed, and after insertion within their said openings are secured in place therein by means of solder.

In the carrying of my invention into prac tice a disk of sheet metal is drawn into the form of an elongated cup, and thel same then placed within suitable dies and expanded laterally until caused to conform thereto, the result being a stem, B, which has the desired exterior form, and is provided with ring-sockets b,that are formed of and integral with the body.

The casestem thus formed possesses strength and durabi1ity,which have not been obtainable by the construction heretofore employed, as its surface has been compressed to shape instead 0f being cut, and its ringsockets iorm part of and cannot be separated from its body.

Having thus fully set forth the nature and merits of my invention, what I claim is As a new article of manufacture, a watchcase stem formed from one piece of metal and having protuberant ringsockets which are a part of and integral with its body, substantially as and for the purpose specied.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of September, 1885.
